NURSING 366 Sherpath week 2 cardiology. Week 2 Basic ekg Match the property of the cardiac conduction system with its description. Property of the cell that allows it to accept initiation of stimulation Excitability Property that moves electrical impulse along a membrane Conductivity Ability of heart muscle to respond mechanically to an impulse Contractility Ability of heart muscle to initiate an impulse, begin stimulation Automaticity List in order the pathway of the normal cardiac impulse starting at the SA node. The impulse causes the atria to contract. The impulse travels from the AV node through the bundle of His. The impulse divides into the left and right bundle branches. The impulse reaches the Purkinje fibers. The ventricles contract. An increase in the rate of cardiac impulse initiation is linked to stimulation of which component? Sympathetic nervous system Which electrolytes play key roles in polarization of the heart cells? Sodium and potassium Which wave on the ECG tracing will provide the nurse more information about atrial depolarization? B A patient asks the nurse, “Why do I need a 12-lead ECG if my heart rate is within normal limits?” The nurse responds by explaining that which heart conditions may be identified by the 12-lead ECG?Select all that apply. Cardiotoxicity Irregular rhythm Myocardial infarction Which ECG component would the nurse measure to identify the total time needed for ventricular depolarization and repolarization of a patient’s heart? D.
